I've been using the ROX 0.8 exclusively for 3 years now. I have one tank with several Angels and another with two Tangs. None of the fish have HLLE in the slightest. I've heard of carbon dust causing HLLE; I believe this product is a good insurance policy against that. Totally worth the money, especially if you buy the 5 gallon bucket when on sale.

Tragic heroBy Jesse Leeon 1/15/2015

Jesse Lee would recommend this product to a friend

This stuff is great. It absorbs quick, and has hardly any dust at all. The price is awesome also. The one fault I can find with it is that my brs gac/gfo delux clogs up very quickly (no socks). It lasts maybe a week and a half before I have to replace it. I work in a remote region and have someone take care of the tank for me (dosing, feeding and skimmer cleaning) but they don't change media. So when I come back it's not really working anymore. Next time I'll get bigger pellets and run this while I'm home.

I've been using this is a filter sock on my hob filter. It does a great job keeping my water crystal clear. A little of this carbon treats a lot of water. I like that since it keeps the price down.

Product caused HLLE in my tangsBy Brenton 12/22/2014

Brent wouldn't recommend this product to a friend

I discontinued use of this product as it caused HLLE in my purple and yellow tangs. After proper rinsing in rodi I would place in my sump, a few minutes later my skimmer would have a tar black sludge developing from the products dust. This caused severe fin erosion in my tangs so I discontinued use. As soon as I stopped using this product my tangs fins grew back and HLLE was gone. I have picture evidence of this if anyone is curious.

I am not an experienced aquarist; but I an say that My tank looks like it has no water in it when I use this stuff and still does after 2 Weeks in a heavily stocked tank. A little bit goes a long way, so is cheap to buy, really.

Worth the extra cost...but still not expensiveBy Bruceon 12/14/2014

Bruce would recommend this product to a friend

Love the extra capacity and low dust with this stuff. I'm short on space under/around my 90g mixed reef so I mix about 1 part High Capacity GFO & 2 parts BRS Premium ROX Carbon in a BRS single reactor. With the mix you don't have the hassle of tweaking the flow to try to maintain the right amount of tumble for the GFO. Been running like this for about 6 months now and it is working well for me on a 2 week change out schedule.

Carbon Rox 0.8By Joeon 12/10/2014

Best carbon on the market I buy the 5 gallon bucket. The water stays crystal clear. It takes about 15 seconds to rinse. I use it in the bulk reef supply Reactors.

Best carbon periodBy Ryanon 12/10/2014

Ryan would recommend this product to a friend

This needs very little rinsing, makes the water crystal clear, and removes its share of toxins. However, one caveat is that if your system is normally dirty and you place this in-line, you may get a few unhappy corals/creatures who had grown reliant on a nutrient rich system. FYI. But I don't think its wise to have a dirty system anyway. This carbon is the best though, I'd run it without question, especially if you've got multiple anemones, etc.

This stuff is unbelievable By Alexanderon 12/8/2014

Alexander would recommend this product to a friend

I am running an unpopulated tank while I get everything set up the way I like it before adding my marine environment.

I was getting calcium and the usual water type buildup until I added this to the filter. Not only has it made the water crystal clear, it's actually slowly removing some of the left over buildup that I missed cleaning. Since adding this carbon I have not had to take a single swipe to clean the unpopulated tank of buildup (a couple months so far)

Very impressed at how effective this is.

Best carbon available.By Nateon 12/8/2014

Nate would recommend this product to a friend

Expensive? Well it costs a lot to buy a 1/2 gallon jug, but this stuff is so good that you don't need to use as much as standard carbon so it really isnt that much more expensive. rinsing is quick as it is very low dust and does a wonderful job. My water has never been so clear.

I've used many different GACs in the past - this is by far the best. Very little rinsing required - I just put it in a BRS reactor and rinse under tap water for about a minute. No fines released into tank water. Two cups last about a month on my heavily stocked 150 mixed reef.

Excellent product, but not my first choice.By Charleson 10/27/2014

I used this product in my TLF reactor. It is an excellent carbon that does a much better than average job of keeping the water clean.
I suggest the white bucket test to check how well your carbon works.
I have only two reasons why this is not my first choice. The size and shape of the carbon particles.
I personally prefer the spherical beads of Sea Chem Matrix carbon. The beads are bigger and seem to have better hydrodynamic properties to me. This might be flow dependent or reactor dependent.. So please know that I would not generalize my anecdote to all tanks.
Both are excellent products, but I had trouble with this one going through filter pads. Neither one has much dust. I think that matrix carbon clumps a little less over time.
You can't go wrong with either product as long as you change it when your bucket test show yellow water.

The Best AC for your tankBy Mohamedon 10/25/2014

Mohamed would recommend this product to a friend

I use the ROX 0.8 in my BRS dual media reactor and I can’t be happier, in the past I’ve used many different activated carbon for my tank and I only liked the ROX, because the small media size I can use more media within the same given space in the reactor and thus I can add more within the reactor. Additionally it clear for me that the media do actually last longer and absorbs more and as a result I have crystal clear water that is hard to distinguish between it and between the top-up water I use.

I use this carbon in a 2 little fishies reactor and couldn't be happier. Does an excellent job keeping water clean. Less is required and in my opinion goes a much longer way than other types of carbon. I've only ever used in a reactor but I'm sure using in a bag will be quite effective.

Been using this Carbon for about a year and it's great. Works very fast - takes that yellow hue out of the water in about a day. Never had any issues with powderizing in my reactor and getting into the water column. Awesome stuff and great for the price. Worth the little extra. Thanks for a great product guys.

Good, but annoyingBy Matton 8/3/2014

Matt would recommend this product to a friend

So, I've been using Seachem Matrix Carbon in my Aquamaxx reactor for a while with no issues. i saw a good deal on the Rox at BRS, and (after all of the good word of mouth I've heard) I decided to try it.

Well, I can say it works well, at least as well as the Seachem Matrix which is a little more expensive.

BUT, it's really painful to use. Rinsing isn't even really that necessary, there's very little dust. The annoying part is that it's very small, and goes right through two filter pads. I had to add a filter sock to the output of the reactor to catch it all (a good amount had made it into my tank by now).

TL;DR - Good carbon, just be ready for it to escape into your tank and add a filter sock to your carbon reactor.

Less is MoreBy Felixon 8/1/2014

Felix would recommend this product to a friend

Went in with a friend to order a large supply. Really worth it as it takes a less quantity to produce crystal clear water than then bigger stuff. Since you use less, it justifies the price for a better product.
